Description

Technical Field

[0001] The utility model relates to the technical field of transmitters, in particular to an air separation transmitter cable connection structure. Background Art

[0002] Transmitters are developed from sensors. Any sensor that can output standard signals is called a transmitter. Standard signals refer to signals whose form and quantity range of physical quantities conform to international standards. Since DC signals have the advantages of not being affected by the inductance, capacitance and load properties in the line and there is no phase shift problem, the International Electrotechnical Commission (IEC) has determined the current signal 4mA~20mA (DC) and the voltage signal 1V~5V (DC) as the unified standards for analog signals in process control systems.

[0003] During the use of the transmitter, it is often necessary to use it with a data cable. The current transmitter is complicated and troublesome when connecting and installing the data cable, which is not convenient for the quick installation of the transmitter cable. Moreover, during installation, its sealing effect is poor and there are gaps, which makes it easy for external impurities to enter the transmitter, reducing the stability of the transmitter. Therefore, we propose an air separation transmitter cable connection structure to solve the above problems. Utility Model Content
